:EPECIIE'ICATION forming part of Letters Patent No. 374,545, dated December 6, 188' Application filed August 29, 1887. Serial No. 248,107. (No model.)

To all whom it may concern:

Be known that I, ALFRED P. LE GROS, of the city of Louisville, county of Jeffersomand State of Kentucky, have invented a new and useful Improvement in Oar-Roofs, (for which Letters Patent of the United States were issued to me on the 3d day of July, 1883,No. 280,635,) of which the following is a specification.

A full, clear, and exact description of constructing my roof is given in the following, reference being had to the accompanying drawings.

The object of my invention is to improve the car-root of a railroad freight or box car in the following particulars: To have the wooden roof covered with well-painted canvas and to protect the canvas from wear, and to prevent the canvas from sticking to the roof-boards in the rabbets, thereby preserving elasticity.

Figure 1 is a representation of my roof as constructed according to my Patent No. 280,635. Fig. 2 is a perspective view of my present improvement thereon.

a, Fig. 2, shows a flat board of proper size, which is well painted on both sides, and is nailed over the canvas between the rabbets.

In the rabbets B, Fig. 2, I place a strip of board or paper or canvas, 0, which is placed under the well-painted canvas,e, so as toprevent the canvas,e, from sticking to the car-roof 0 board (1, thereby preserving elasticity.

The manner of constructing my roof is explained in Letters Patent No. 280,635, except i the above improvement, which, having been explained,

I desire to claim and protect by Letters Patent 7 1. The combination of the rabbeted roofboards, the painted canvas folded and fitted into the rabbets,and the canvas or paper Strip 0, fitted in the rabbets beneath the fold of the canvas, as and for the purpose set forth.

2. The combination of the rabbeted roofboards,the painted canvas sunk and fittedinto the rabbets, the paper or canvas strip, and the 4 5 v surface-boards a, as and for the purpose set forth.
